The overall objective of this PhD project is to investigate the impact of environmental change on the evolution and demography in arctic species. This will be done through genetic analyses on both modern samples and on DNA retrieved from fossils up to 50 000 years old. The resulting genetic data will be integrated with information on past distributions and climates, as well as back-casted species distribution models. Specific questions that will be examined in the project include i) the timing of extinctions and demographic change in relation to past climate fluctuations, ii) when and where populations diverged and species evolved, and iii) to what extent local populations tracked changes in habitat availability when faced with climate change. Potential model species include lemmings, arctic foxes,reindeer and ptarmigan. The long-term aim of the project is to provide increased knowledge on how habitat change drives the speciation and extinction processes and, on a more practical level, to increase the accurac of models used to forecast the impact of future climate change on biodiversity.
The project will be done within the ancient DNA research group at the Molecular Systematics Laboratory (MSL) in the Swedish Museum of Natural History. A part of the research carried out by the PhD student will be done within the cross-disciplinary research network CLIMIGRATE, funded by the European Union’s FP7 ERA-NET program BiodivERsA. The PhD degree will be awarded in Systematics and Evolution at the Department of Zoology. Dr. Love Dalén at the Swedish Museum of Natural History (MSL) will be the main supervisor. Prof. Anders Angerbjörn at the Department of Zoology will be co-supervisor.
Qualifications:
To be qualified for research studies in systematics and evolution the applicant must have completed a research degree (e.g. Master’s), or have passed in at least 120 hp (2 years) of biological studies, including an approved independent project in systematics and evolution of at least 30 hp at advanced level (”examensarbete”). Applicants who have in principle acquired the corresponding competence in Sweden or abroad, are also qualified. That is, applicants who have a Master’s degree (”examensarbete”)in an equivalent subject that is considered appropriate for this project are also encouraged to apply.
